U.S. Sen. Elizabeth Warren, a hero to the progressive left, has endorsed Democratic congressional candidate Zephyr Teachout, her campaign announced in a fundraising email.

“Everyone from billionaire hedge fund managers to the Koch brothers’ corporate PAC is pouring money into defeating Zephyr Teachout,” the Massachusetts senator said. “Why is she one of the biggest targets in the country? Because Zephyr isn’t for sale. They know Zephyr will fight to protect social security from Wall Street. She’ll take on bad trade deals. She’ll help hold big banks accountable and get them lending to farmers, families, and small businesses again.”

The news isn’t surprising in part since Teachout and Warren have similar resumes as academics, and Teachout has the potential of modeling her career in the House after Warren’s advocacy in the Senate.

Warren, in the email, certainly seems to think Teachout will have a similar approach to the job if elected.

“I want to serve in Congress with Zephyr so we can put people before powerful interests. Zephyr has the kind of truly independent voice we need,” she said.

Teachout is running in the battleground 19th congressional district against Republican John Faso. GOP incumbent Chris Gibson is retiring this year.

Updated: The National Republican Congressional Committee in a statement pointed to the donations from liberal and wealthy hedge fund managers like George and Jonathan Soros.

“Not only does Zephyr Teachout think Upstate voters are dumb, but her radical liberal friends like Elizabeth Warren think they’re dumb, too,” said NRCC spokesman Chris Pack. “Elizabeth Warren and Zephyr Teachout must only take issue with billionaire hedge fund managers when they aren’t donating to their campaigns, and that makes them both pandering hypocrites.”
